The display optical system comprises an optical system including a first optical system and a second optical system. The first optical system includes a first surface decentered with respect to a central principal ray, and a second surface which reflects again light reflected on the first surface to the first surface. The first surface reflects the central principal ray incident on the first surface again from the second surface substantially to the opposite side to the previous reflection with respect to a normal on a hit point of the central principal ray. The first optical system directs light to an eye of an observer. The second optical system directs the illumination light to the image forming element and directs the display light to the first optical system.

摘要： An optical system is disclosed with which higher magnification can be easily achieved and aberrations can be favorably corrected, yet is compact. The optical system includes a plurality of optical surfaces including a first surface which has at least a reflective action, a second surface reflecting the light rays reflected by the first surface back toward the first surface, and a diffractive optical surface. The first surface reflects a central field-angle principal ray, which comes from the second surface and is again incident on the first surface, to the opposite side of the previous reflection with respect to a normal at a hit point of the central field-angle principal ray on the first surface.
